PSD4/RPN-10 binds to this protein by expressing the LALAL (“L-A-L-A-L”) motif. This protein’s activity can be promoted by incorporating the DCAF (“decaf”) receptor into a “molecular glue” for recruitment of the CUL4-DDB1 (“cull-four D-D-B-one”) complex. This protein’s ability to bind to a substrate is enhanced by a complex composed of Skp1, Cullin, and F-box subunits. Proximity-promoted addition of this protein to other molecules can be facilitated by PROTACs. About 4 monomers of protein must be attached by lysine (10[1])linkages before its primary function is carried out. A series of 3 ligases add (10[1])this protein to other proteins to mark them for degradation in the (-5[1])26S proteasome. For 10 points, name this 76-amino acid “molecular kiss (10[1])of death” whose name derives from its expression in nearly all (10[1])eukaryotic (10[1])cells. ■END■ (10[1]0[2])
